Iranians show their hands, with writing in Persian in support Supreme Leader Ayatollah Ali Khamenei, denouncing the U.S. and one of them with the word "Nuclear Scientist," during an annual state-backed rally in front of the former US Embassy in Tehran, Iran, Friday, Nov. 2, 2012. The rally marks the Nov. 4, 1979, storming of the building by militant students who held 52 Americans hostage for 444 days to protest U.S. failure to hand over the toppled shah Mohammad Reza Pahlavi to Iran for trial. Gen. Mohammad Reza Naqdi of the powerful Revolutionary Guard, not shown, addressed the rally saying the U.S. must annul the CIA, pull out its warships from the Persian Gulf and dismantle its military bases from 50 countries around the world if it wants to restore ties with Tehran.
